Mobilians On Bikes will get suitably gory for the third annual Zombie Ride through downtown and Midtown on Friday, Oct. 25, starting at 7:30 p.m. The starting point is Delta Bike Project, a nonprofit bike cooperative at the corner of St. Louis and Warren streets.

For those who aren’t hip to zombie fashion, organizer Niklas Hallberg suggests arriving in dirty clothes “to look like you just got out of the ground.” In past rides, he added, some bikers have gone so far as to add fake flesh dangling here and there.

But of course, safety is important, even for the Riding Dead. Bikers should take care to keep anything from getting caught in the spokes, and helmet and bike lights are recommended.

Several amateur makeup artists will be on hand at Delta Bike Project, beginning about 6 p.m., to assist with standard zombie makeup -- fake blood, blacked-out eyes, ghostly pallor -- for a small fee, he said.

MOB member Ben Brenner has retrofitted a child’s bike trailer with a sound system to add rolling tunes to the Zombie Ride. The idea of music came from West Coast "bike party" groups, Hallberg said, and if the tunes are a hit, MOB will plan more fourth-Friday rides, starting next month.

The ride will be about 6 miles long and will take about 90 minutes. It’s something any able-bodied adult or older child can do, Hallberg said. “It’s not a race; it’s more of a cruise to town.
